Subject [jira] Commented: (HIVE-458) Setting fs.default.name incorrectly leads to meaningless error message
Date Tue, 22 Dec 2009 03:26:18 GMT

    [ https://issues.apache.org/jira/browse/HIVE-458?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12793483#action_12793483
] 

Paul Yang commented on HIVE-458:
--------------------------------

Missing example from above:

{code}

hive> set fs.default.name=http://wilbur21.labs.corp.sp1.yahoo.com:8020;
hive> show tables 'tmp_pyang_*';
OK
tmp_pyang_dim_api_data
tmp_pyang_lv
tmp_pyang_null
tmp_pyang_output
tmp_pyang_t
Time taken: 0.235 seconds

hive> set fs.default.name=|http://wilbur21.labs.corp.sp1.yahoo.com:8020;
hive> show tables 'tmp_pyang_*';
FAILED: Unknown exception: null

hive> set fs.default.name='http://wilbur21.labs.corp.sp1.yahoo.com:8020;
hive> show tables 'tmp_pyang_*';
FAILED: Unknown exception: null

{code}

(behavior is dependent on URI.create() )
